to similar parts a re secured In work where it is desired that they run inJthe vertical plane or parallel with the chucks, bearings 13 and 14 may be lifted off and reversed on supports 21. Such a change might be desirable in grinding.

19 designates the idler shaft plate, one bn each side of the machineand which has a slot in one edge to adjust and secure the idler shaft carrying idler pulley 20; this plate is reversed when the bearings 13 and 14 are reversed on the supports '21 to give the proper lead of belt.

21 designates the supports for the bear ings, preferably round, especially at their 15 ends, and loosely fulcrunied at their lower ends and loosely supporting the bearings at their upper ends.

22 designates a bracket through which 0perates an adjusting screw. This screw is adjusted by means of hand.wheel, 23. The other end of said screw is pivoted to sup ports 21. There is a spring between sup- .ports' 21 and the end of the screw, which springs tend to keep the buffs or grinders up to their work. This spring is normally in compression.

A cone pulley 24 isplaced on the main shaft 8 and is adapted to drive the cone pulley 25' on the operating shaft by means of a belt. A bevel pinion 26 is placed on i the operating shaft and drives the bevel gear 27 on shaft 28 to which it is secured. Shaft 28 drives the chucks 4 and 5 by means of pinion 29 and intern'iediatc gears 30.

()n main shaft 8 is secured pulley 31 which drives pulley 32 by a belt. Pulley 82 drives shaft 50 on which shaft is secured pulley 51 which drives shaft 58 by means of a. belt operating on the pulley 52 secured to 0 said shaft 53. The shaft. carries the buff 54. A curved lever 34 is fulcrumed on base 1 at the point 33. The loi'er yoke forms a bearing for the shaft 50 lipon which pulley 32 is mounted, and is fdlcrumed to curved lever 34.

36 designates the upper yoke, fornung a bearing for the shaft 53 upon which half 54.

is mounted.

37 designates an adjusting screw operated by a handle for operating curved lever 3% thereby adjusting the position of buff 54 ,with reference to the work coming out. D The lower yoke 35 and upper yoke 36 are 7 adjustably secured together by the member 45 by a screw-threaded connection. By reference to Fig. 2 it will be seen that the yoke 35 is adjusted to receive the member 45 which is screw-threaded thereon. There are lock nuts on the member 45 by which it is held securely in position when adjusted. -When it is desired to change the angle of the bad 54 to the work the lock nuts are loosen *d and the buff may then be turned to the e sired angle, and when in position may be The elevation of the buff can then be adjusted by means of the screw 37. This adjustment permits buif 54 to be adjusted at any desired angle to the work coming out which will produce a longitudinal grain on the work or to give amirror finish.

38 designates bearings secured to base 1 through which operates-shaft 28. On shaft 28 is secured worm 39, which worm drives worm wheel 40 mounted on shaft 41.

42 designates an eccentric secured to shaft 41, and operates eccentric casing 43, to which casingone end of connecting link 44 is adjustably secured; the other end of connecting link 44 being loosely pivoted to the member 45. Eccentric 42 causes buff 54 to move substantially longitudinally relative to the the adjustable securing of fulcrum 46 to chuck bearing 3. In chuck bearings 2 and 3 is secured sleeve by means of set screws 56, see Figs. 4 and 5. The chucks at each end of the machine are similar, excepting as to the speed of the feed rollers, therefore the description of one will be sufficient. 57 is a sleeve formed on chuck 4 and operates in chuck bearing 2 around sleeve 55.

Three pin shafts 58 are journaled in the chuck as shown. in Fig. 4, and are held in place by nuts ()n shaft 58 is journaled pinion (S0,- to which pinion is secured worm (31. Pinion (30 is driven as the chuck rotates by stationary gear (32 which is integral with V sleeve 55. Intermediate gear 30 drives the chuck by means of chuck gear 72 which is formed integral with the chuck.

()n pin shaft is secured roller bracket 63, which carries roller shaft- Gl. \Vorm wheel 65 which is operated by "worm (i1 drives roller shaft 164 to which it is secured. The rollers 66 are preferably made of vulcanized rubber and are secured to and operated by roller shaft (H. ()n pin shaft 58 is secured a sector lever (37, on the end of said lever is formed a segment of a gear 71 whicg is operated by gear (38.

(39 is a pinion mounted on a projection of the hub of chuck 4, its shaft extending through said projection amlbcing provided with a squared end at 73 1.0 passive the Gear 68 is mounte in the chuck behind stationary gear 62 and wrench 74. Pinion (39 operates gear (38, si-

multaneously opening thechuck when it is fixed thereby tightening up the lock nuts. desired to remove or introduce work, thus 66 by means of wrench Hoperating against the tension of sprin 70. The machine beingstartcd, the work is rotated by means of chuck' i and at the same time is fed longi- 'tudinally by means of rollers 66.

17 and 18 may be grind stones, emery or other hard grinder. or may be soft buffs or other polishing surfaces as desired. They may he adjusted to work on an angle as shown in Fig. 1 when butting, or they may be reversed to work pa rallel'w'vitlr the face of the chuck when grinding. Grinders 17 and 18 are adjusted by hand wheel-nuts 23, and are kept against the work by the springs operating in the spring brackets. As the work goes through the machine it is caught by chuck 5. the rollers of which work in. the same direction but with a less speed than 'tllOS}: in chuck 4, with the result that short pieces |n being fed either on a mandrel or in:

shortlengths connected by plugs infthcir ends are kept forced together while inthe machine. As the work comes out-of the machine it comes in contact with and is worked on by buff 54, which bufl'inoves to and fro longitlu-linally of the workQas well as rerolving. and is adjusted to the work by adjusting screw 37. as to height, and may be given any angle to the work desired; this buff removes circular marks. 7

49 is 'an idle wiping buff which may be adjusted to the work as desired, and also operating as a back rest for the buff under it.
